mine is with Vilayer, very good and fast not had any big problems! If you want it on the main hive then all you do is put a request ticket in and its sorted for u. Very quick too within 24 hours response ive had.

Basicly with vilayer private servers they share the same hive i.e where characters are stored i.e weapons / inventory.
So a player can move from 1 vilayer private server to the next one & keep there gear.
I assume its the same with hfb's servers aswell.

U wont be able to password the server or lock it with vilayer private server.

As far as banning people / kicking them, go for it...
I kick / ban people for talking over von in side channel. And i also check the logs like normal to ban hackers from the server..
